It did not register when i checked in that the flight was leaving from gate 203It was not until i got to the lounge that i was told to go to T3. Another pax across the aisle had the same problem but managed to get past Guy the Gorilla on security. When he got to the lounge and complained he was told that he must have made a mistake/misheard what he was told to do. He was really pleased when 6 - 7 pax behind him complained that they had also been told to proceed to T3. but managed to get past security. It turned out that the lounge was packed, considering that 2 flights were leaving from T3, Doha and Muscat, makes you wonder?? The crew confirmed that these two flights were the first real live trials prior to the official opening on the 14th. The only refreshments that were available were from the Cosi Coffee shop, this opened at 07.00am. They only had coffee either with or without milk + tea. Their coffee machine had broken down. The choice of food was muffin, muffin or muffin. Starbucks was on the point of opening at 07.30. The EK ground staff had their normal unhelpful attitude. I mentioned it would be a nice gesture to give me a food and drink voucher. I was told the terminal was new and i had to expect these problems I ended up paying for the coffee, i passed on the muffin, muffin or muffin. At least i had plenty of time to go on a voyage of discovery. There are a lack of toilets and inside they are really small. There are 4 food/beverage outlets close to gate 203 but only one M/F toilet . The signage for the toilet is also poor. The sign for the toilet from gate 203 takes up the corridor. Turn right and right again, this takes you down the opposite corridor past the duty free past the food outlets and down to the same toilets. The next set of toilets are a fair old walk away. The business and first class lounges look really spacious. Not sure about the lounge access being so open, and like the current setup there is only one desk so no doubt when it is busy you will get the same bottleneck. It seems as though the open bar concept is not in place. The bars appeared to set up for serving by staff. Not sure if they will change the speed of the escalators, when you walk on to them they are moving so slow it takes you by surprise. Boarding took forever, the 1st office made an announcement confirming that this was a trial departure and some of the passengers had got lost trying to find the gate. Ended up leaving 30 minutes late.
